HARVESTER-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 535,249, dated March 5,1895. Application filed January 17,1393- Serial No. 459003. (No model.)

To all whom it may concern:

Be it known that I, MAURICE KANE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Harvester-Elevators, of whichthe following is a specification.

This invention relates to improvements in harvester elevators, and it sobject is to arrange the upper apron or belt of the elevator so as tomaintain its lower side in practically a straight line, while thevertical height of such apron-above the drive wheel is as low aspossible.

The invention consists in substantially the arrangement and constructionhereinafter pointed out, and particularly set forth in the claims.

The drawing represents a vertical longitudinal section of a harvesterelevator embody ing my invention.

The drive wheel A is of the usual construction and need not beparticularly described.

The platform conveyor is designated by the letter B, but only theportion of the same next the discharge side of the machine isillustrated, and this, also, is of common and well known construction.

The harvester elevator comprises two aprons or belts, an upper apron Cand a lower apron D; the rollers for both being suitably journaled inthe frame E. y

The lower apron D extends from adjacent to the discharge end of theplatform conveyer to near the upper inner side of the drive wheel. Theupper apron C begins at such point above the lower end of the lowerapron as will atford a sufficient space for the requisite quantity ofgrain to pass between the aprons, and then extends to such a point abovethe drive wheel as will afford an approximately similar space betweenthe outer end of thelower ply of such upper apron and the bridge ordeck. A third or guide roller G is provided for the up per ply of theupper apron and is located in the instance shown directly above theupper roller of the lower apron. The under ply of the upper apron isdesigned to normally extend in an approximately straight line whichgradually approaches the upper line of the lower apron and withoutactually touching extending beyond the upper and outer end of such lowerapron to the point above the drive wheel or bridge before indicatedwhich bridge is designated by the letter H and extends beyond the lowerapron over the drive or master wheel as shown. This arrangement of theparts as above described admits the greatest possible displacement ofthe under ply'of the apron in the passage of the grain with the bestgripping and feeding action. This will be understood by reference to thedotted lines in the drawing and a comparison of the construction hereindicated with that shown in my former Patents No. 487,223, datedNovember 29, 1892, and No. 456,722, dated January 5, 1892. The lowerdotted line is designated by the lettera and the upper one by the letterZ) and these are designed to show two positions of the lower ply of theupper apron. If there was no third roller then the lower ply could notbe lifted beyond a straight line which would join the upper peripheriesof the two rollers of the apron. lower ply of the apron was carriednormally by a ledge out of a straight line, then if the grain was thinand the mass presented at one time to such aprons correspondingly small,the grain might lodge and be difficult to feed forward, by the aprons,but by carrying the lower ply in astraight line from the lower to theupper roller of the upper apron, and providing a third roller to liftthe upper ply a sufficient distance, a proper feeding or gripping actionfor the light grain can be had, and at the same time sufficient roomprovided for the greatest necessary displacement. In other words, suchan apron as is last mentioned is adapted to both light and heavy grain;to light because it gives a good gripping action, and to heavy becauseit allows sufficient displacement. At the same time by the combinationof a straight lower ply and a third roller the outer end of the apronmay be brought sufficiently low to form a proper sized delivery throatand thus insure the proper feeding of the grain over the bridge or deck.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

1. A harvester elevator comprising a lower If there was a third roller,but theapron and an upper apron, the lower ply of which latter extendsina straightline, and the upper ply of which is deflected upward bymeans of a guide or roller; substantially as and for the purpose setforth.

2. A harvester elevator comprising alower apron and an upper apron, thelower ply of which latter extends in a straight line and the upper plyof which is provided with a guide or roller arranged over the upperouter supporting roller of the lower apron substantially as and for thepurpose set forth.

3. Aharvesterelevatorcomprisingan upper and a lower apron the lower plyof the former being on a straight line such line passing close to thedischarge end of the lower apron and the upper ply of the upper apronbeing defiected upward over athird or idle roller; substantially as andfor the purpose set forth.

4. A harvester elevator consisting of an upper and lower apron, thedischarge side of the latter being located grainward of the masterwheel, a stationary deck or bridge extending upward and across the topof the master wheel thence downward to the binder deck, in combinationwith an upper apron the lower or receiving end of which is located somedistance from the upper ply of the lower apron and having its lower plyextending in a straight line and close to the stationary deck, the upperply of said apron being deflected upward by means of the idle roller;substantially as and for the purpose set forth.

5. In a harvester elevator, in combination with the grain supportingelement of the elevator, an endless apron carrier overhanging suchelement, having its lower ply extending normally in a direct lineoblique to the surface of said grain supporting element, and closethereto at the highest point of the latter, said carrier being providedwith a guide roller for its upper ply, located above a direct linebetween the extreme rollers; substantially as and for the purpose setforth.
